We never got a chance to put it on a dynojet. We only tuned it on the in-house Mustang dyno and it did 622whp. The dyno graph is on our Facebook page. This is about 60whp more than the standard 62mm customer cars that put down 650whp on Dynojets. The extra power came primarily from running on straight e85+meth. 27psi of boost with a pretty aggressive timing curve. Definitely not for the risk averse.
